The Wireless Body Area Networks (WBANs) are a special case of
the Wireless Sensor Networks (WSNs) and, in general, are responsible
for gathering and transmitting biometric data from a given
patient. One of the features of the WSNs is the self–configuration;
i.e., the capability that a given parameter can be adjusted regarding
some occurrence in execution time. As stated, the objective of the
WBANs is the gathering, through several sensors, of biometric data
of a patient. In general, because of possible daily activities and/or
pathologies, some sensors can be more demanded (or required) in
certain periods of the day. In these situations, information of these
mentioned sensors are more relevant and require larger data delivery
priority. Thus, we propose QoSBody-AODV, a variation of the
AODV routing protocol, which performs the dynamic adjustment
of the message’s priority, turning the network functioning to be
sensitive to the physical activities performed by the patient, as well
as pathological information.
